By discussing the drug thing, you have been distracted from the premise, which is the Myth of the Labor Shortage (Even Though Unemployment is Through the Roof).
It is currently fashionable to admit that you can't seem to hire or retain people, while also admitting that you don't know why and you don't know what to do about it. Contrast this with the willingness of companies to advertise that they can't do other basic things like make sales, ship products, or balance their books. This reveals that one of two things are going on:
--these businesses are clueless and probably run by stupid people, or millennials
--these businesses are manufacturing a crisis in order to agitate for some political handout
“We could take on twice as many projects if we had more suitable workers,”
Compare:
"we could grow twice as many soybeans if we had more arable acres"
"we could fab twice as many microchips if our factory had more throughput"
"our taxi fleet could collect twice as many fares if we could put more cars on the road"
Why don't we see articles like the above? Because nobody cares about your business problems. "We could make more money if we could make more money" is not news. Here are my suggestions for sufferers of TMOTLSETUITTR: if you need to hire more people, try to raise your wages, or use your existing people more efficiently, or retain the people that you have better, or invest in capital so that you don't need as many people, or lean our your operation to reduce waste, etc. etc. i.e. do the f'ing job that your MBA supposedly equips you do to and stop whining about your labor problems.
I swear that we are in a generation of business managers who just discovered that personnel management is important and hard, but what's more, they somehow think that it's only important and hard now, rather than having been important and hard since the beginning of time. Either that, or they are agitating for more foreign workers, which is usually the case, such as when California companies insist there is a programmer shortage every few months and they are all going to go out of business if we don't import more programmers, despite every programmer knowing about 3 people who are looking for work.
